The RF380R with MLFB 6GT2801-3AB10 allows the transmission output power to be set
with the aid of the "distance_limiting" input parameter (you will find more detailed information
in "Function manual FB 45
(https://support.industry.siemens.com/cs/ww/en/view/21738808
)"). For this, values from
approx. 0.5 W to approx. 2.0 W can be set in 0.25 W increments. Depending on the setting,
the change to the transmission output power increases the performance in the lower
operating distance (low performance) or in the upper limit distance (high performance).
The "distance_limiting" range of values is from:
● 02 (= 0.5 W) through
● 05 (= 1.25 W; default value) to
● 08 (= 2 W).
Note
A 'distance_
limiting' value setting outside of the range of "02 to 08" leads to the default
setting 5 and does not generate an error message.
You will find more information on this subject in the chapter "
Minimum clearances (Page 59
)"
section "Minimum distance from reader to reader".
You will find precise information about the parameters in "Product Information "FB 45 and
FC 45 input parameters for RF300 and ISO
transponders"
(
